What is spam?
Spam is unwanted email, also known as junk mail. Modern email clients like Gmail automatically detect messages likely to be spam and sort it into a separate folder.
How does spam work?
Spam is often sent unsolicited to hundreds or thousands of people at once. Lists of email addresses are acquired by spammers through both legal and illegal means.
Spam mail often contains links disguised as a familiar website but actually lead to phishing sites and malicious sites infected with malware.
